PATENT LElVlS S. \VIIITING, OF ASIILAND, ASSIGNOR OF ONE-HALF TO HORACE H. \VHITING, OF CANTON, OHIO.

CLOVER-H ULLER.

SPECIFICATION forming part of Letters Patent No. 447,743, dated March 3, 1891.

Application filed June 5, 1890. Serial No. 354,398. (No model.)

To all whom, it may concern:

Be it known that I, LEWIS S. \VHITING, a citizen of the United States, and a resident of Ashland, county of Ashland, State of Ohio, have invented a new and useful Improvement in Olover-Hullers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to c1over-hullers; and it has for its object to provide a support for the hulling-cylinder and means by which quick and easy access may be gained to the cylinder for the purpose of repairing the same, as well as for the removal of obstructions.

lVith these ends in view my invention consists in certain features of construction and combination of parts, as will be hereinafter described, and pointed out in the claims.

Figure 1 is a vertical longitudinal View through the front portion of the frame and a transverse section of the thrashing and hulling cylinders, showing the relative position of these parts in the frame. Fig. 2 is an end View of the hulling-cylinder frame and concave. Fig. 3 is a sectional view through the cylinder and concave-supporting hinge.

As my invention is applicable to many of the clover-hullers now in use and well known to the builders and usersof such machines,I will proceed with a description of my invention, referring to the frame, thrashing-cylinder, and other parts only as conjunotional thereto.

A represents the thrashing cylinder, by

which the seed-bolls are thrashed from the straw, after which by well-known appliances the seed-bolls are conveyed to the hulling-cylinder. This description will serve to call attention to the location of the two cylinders,

the hulling-cylinder being below and to the The cylinder-supporting frame E is composed of the cast metal end pieces at having an outwardly-projecting flanged portion a to form a support for the cylinder-shaft journalboX a and an arm portion d having a perforation a to receive the supporting-shaft D, and an outwardly-projecting flanged portion a, to which the ends of the concave stavesF are secured by the bolts a thus forming a rigid frame, in which the hulling-cylinder B is supported.

To provide for opening the concave, the front staves a have integral arms a toreceive the end portion 1) of the shaft D, about which it hinges. The end piece ct is provided with lugs Z), between which is pivotally secured an eyebolt b the lower or free end of which swings into a notch b in the end of the stave a and the nut b is turned up against the stave to hold it in position.

On the side plate a there are provided lugs b and on the end piece a of the cylinderframe corresponding lugs b. Between the former is pivotally secured an eyebolt b that will swing between the lugs I) when the cylinder-frame is in normal position, the nut 13 to take under the lugs b to hold the frame and cylinder in operative position. Then arranged as hereinbefore described, by loosening the nuts b the eyebolt may be swung out from the lugs b and the cylinder-frame and cylinder dropped down, as shown in Fig. 2, exposing the upper portion of the cylinder for the purpose of repair, and to open the concave the nut b is turned back a distance, the end of the eyebolt b swung out from the notch in the stave a and the stave released to swing down and out about the shaft D, thus form' ing an opening into the concave and the front lower part of the cylinder for the purpose of repair or for the removal of obstructions.

Having thus fully described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a clover-huller, the concave consisting of end pieces a, staves F, means for securing them to the end pieces, a concave stave a having a hinged connection with the machine with one and removably secured with the other end to the body of the concave, in combination with 'means for securing said concave in operative position to the machine, substantially as set forth.

2. In a clover-huller, the concave consisting of end pieces a staves F, means for securing them to the end pieces, a concave stave a having a hinged connection with the machine, and an eye-bolt pivotally secured to the end piece a and having its free end adapted to IO engage the concave stave, in combination with means for securing said concave in 0perative position to the machine, substantially as set forth.

In testimony whereof I have hereunto set my hand this 26th day of May, A. D. 1890.
